Ford Control Pack Information/Help

[juddster]

Hoping to get some help on some details on a Gen 2 Coyote control pack (Manual Transmission). I don't have access to a control pack.

If someone has access to the control pack wiring (uninstalled control pack or easy access to the wiring) I'd like to ask for some help on tracing where some of the wires plug into PCM.





The three wires I am trying to trace from the Control Pack connector (C160B) to the PCM connectors (C175B/E) are underlined in yellow below. Start - Light Blue, Ignition - Light Green and Green - Fuel Pump
The fuel pump wire will go through a relay before continuing on to the PCM. The others I think also go through a relay or fuse.

Here are the two connectors on the control pack that go to the PCM

Juddster, The c160b, aka pigtail, is the main integration point with the Ron Francis harness. That is, of course, if you're using the RF harness.

There are a lot of questions that arise in my mind, based on what you wrote in your initial post.
1. what do you have for a coyote wiring harness? Is this the control pack from the factory, or is this something that you harvested from a donor vehicle?
2. have you obtained (or sought) the instruction sheet from ford? do an online search for "IS-1850-0519" that will answer many questions.
3. while the three wires you mention are important, there are other connections you'll want to make - i.e. integration points. A good source of information is any of a number of build threads by any of the coyote gang.

That said, fuel pump relay out integrates with the brown fuel pump wire in the rf harness. let the pcm control the pump. light blue goes to blue efi/crank wire in rf harness. the light green wire goes to the rf harness orange efi/coil wire. hope this helps.
